The invention relates to vibrators, and more particularly to a vibratorhaving a reciprocating massage cushion operated by an electro-magnet.

It is an object of the invention to provide an electric vibrator havinga vertically disposed electro-magnet, the reciprocating core or armatureof which supports a massage cushion for rapidly vibrating the same.Another object is to provide a vibrator of the character referred to inwhich spring means is associated with the armature acting against thepull of the magnet.

A further object of the invention is the provision of a Vibrator of thischaracter in which the armature is swivelled within the magnet.

A still further object is the provision of such a vibrator which isadaptedfor the well known method of Swedish massaging.

Another object is to provide a vibrator which may be easily and readilyadjusted to obtain the desired vibration. I

It is still another object of the invention to provide a vibrator whichis of simple and inex pensiveconstruction and flexible in operation,

A further object is to provide a vibrator in which several types ofmassage cushions are easily and readily interchangeable.

Still another object is the provision of a vi;- brator having a massagecushion provided with expansion springs through which the operator mayplace his fingers for giving a Swedish massage.

The above objects together with others which will be apparent from thedrawings and-following description or which may be later reierred.

to, may be attained by constructing the improved electric vibrator inthe manner illustrated in the accompanying drawings, in which- Fig. 7 anelevation of a modified form of shell or asi ap l ed t the m o ed ratorSimilar numerals refer to similar parts throughout the drawings.

. .Beferri-ng first tothe ,form of vibrator sh w;

in Figs. 1,2 and 3, a cylindric shell 18, which may be formed of sheetmetal or other suitable material, is provided for housing theelectro-magnet and armature of the improved vibrator.

The lower end of the shell l may be rounded as indicated at II, andprovided with a central aperture I2, through which the armature isadapted. to reciprocate, as will be later described.

A flanged cover or lid I3 is provided for covering the upper open end ofthe shell l0, and is arranged to be held in position upon the shell bymeans of the screw M.

The magnet includes the inverted U-shape pole piece [5 formed of softiron and connected tothe shell ID as by the screws IS. The magnet 0011or solenoid H is mounted within the pole piece and the cross member I8is connected to the lower ends of the pole piece l5 beneath the lowerend of the magnet coil.

An adjusting screw [9 is threaded through the top of the pole piece It:and a lock nut is provided thereon for holding the screw in addustedposition. This adjusting screw is provided with the internal threads 2!into which the screw I4 is threaded for holding the cover 13 upon theshell.

The magnet coil ll has a central vertical opening 22 therein and thereciprocating armature 23 is mounted for vertical sliding movementtherein.

This armature has the reduced lower extension 24 slidably locatedthrough an aperture 25 in the cross piece 18 and an adjusting nut 26 ismounted thereon at a point spaced below the cross memher, a compressionspring 27 being located around the reduced extension 24 of the armaturebetween the cross member l8 and the nut. A further reduced extension 28may be formed upon the armature below the nut 2i; for sliding movementthrough the aperture I2 in the lower end of the rounded bottom portionll. of the shell. This extension terminates in a reduced threadedportion 29 by means of which themassage cushion may be attached to thearmature.

As shown in Figs. 1, 2 and 3, this massage -cushion may include achannel-shape member 3,0 of stamped sheet metal or the like provided atits side edges with down turned flanges 3! and having a. centralthreaded opening 32 or nut 33, or both, to receive the threaded lowerend 29 of the armature.

The sponge-rubber cushion 34 is cemented or otherwise mounted within theinverted channel; shape holder 3i! and extendsa considerable dis- .tancebelow the flanges 3| ther of.

Eyes or hooks 35' are formed at the ends of tro-magnet within the shellincluding a U-shape pole piece, means detachably connecting the legsofthe pole piece to the sides of the shell, a coil supported within thepole piece, a reciprocating armature mounted within the coil andextending through the lower rounded end of the shell, a massage cushionupon the lower end of the armature, an adjusting screw located throughthe pole piece for contact with the adjacent end of the armature tolimit the throw of the armature in one direction, a lock nut for holdingthe adjusting screw in adjusted position, said adjusting screw beinginternally threaded, a removable April 11, 1944.
